Materials Data on CeZr7O16 by Materials Project
CeZr7O16 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. Ce4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Ce–O bond distances ranging from 2.20–2.46 Å. There are five inequivalent Zr4+ sites. In the first Zr4+ site, Zr4+ is bonded in a distorted body-centered cubic geometry to eight O2- atoms. There are a spread of Zr–O bond distances ranging from 2.10–2.46 Å. In the second Zr4+ site, Zr4+ is bonded in a distorted body-centered cubic geometry to eight O2- atoms. There are a spread of Zr–O bond distances ranging from 2.09–2.45 Å. In the third Zr4+ site, Zr4+ is bonded in a distorted body-centered cubic geometry to eight O2- atoms. There are a spread of Zr–O bond distances ranging from 2.08–2.52 Å. In the fourth Zr4+ site, Zr4+ is bonded in a distorted body-centered cubic geometry to eight O2- atoms. There are a spread of Zr–O bond distances ranging from 2.10–2.47 Å. In the fifth Zr4+ site, Zr4+ is bonded in a distorted body-centered cubic geometry to eight O2- atoms. There are a spread of Zr–O bond distances ranging from 2.10–2.45 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded to one Ce4+ and three Zr4+ atoms to form a mixture of distorted corner and edge-sharing OCeZr3 tetrahedra. In the second O2- site, O2- is bonded to one Ce4+ and three Zr4+ atoms to form distorted OCeZr3 tetrahedra that share corners with twelve OZr4 tetrahedra and edges with five OCeZr3 tetrahedra. In the third O2- site, O2- is bonded to four Zr4+ atoms to form a mixture of distorted corner and edge-sharing OZr4 tetrahedra. In the fourth O2- site, O2- is bonded to one Ce4+ and three Zr4+ atoms to form a mixture of distorted corner and edge-sharing OCeZr3 tetrahedra. In the fifth O2- site, O2- is bonded to one Ce4+ and three Zr4+ atoms to form a mixture of distorted corner and edge-sharing OCeZr3 tetrahedra. In the sixth O2- site, O2- is bonded to four Zr4+ atoms to form a mixture of distorted corner and edge-sharing OZr4 tetrahedra. In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to four Zr4+ atoms. In the eighth O2- site, O2- is bonded to four Zr4+ atoms to form distorted OZr4 tetrahedra that share corners with fourteen OCeZr3 tetrahedra and edges with four OZr4 tetrahedra. In the ninth O2- site, O2- is bonded in a 4-coordinate geometry to four Zr4+ atoms. In the tenth O2- site, O2- is bonded in a 4-coordinate geometry to four Zr4+ atoms. In the eleventh O2- site, O2- is bonded to one Ce4+ and three Zr4+ atoms to form a mixture of distorted corner and edge-sharing OCeZr3 tetrahedra. In the twelfth O2- site, O2- is bonded to one Ce4+ and three Zr4+ atoms to form distorted OCeZr3 tetrahedra that share corners with thirteen OCeZr3 tetrahedra and edges with five OZr4 tetrahedra.
